406 Forged Alloy Steel D-Ring, 22.2 kN

The 406 is forged from alloy steel and heat treated, then 100% proof loaded to 3600 lbs (16 kN), so every ring is load-checked before it leaves production. The minimum breaking load is 5000 lbs (22.2 kN).

Those two figures are the values North American harness specifications typically call for in D-rings, which makes the 406 a natural fit for dorsal, sternal and side D-rings on full body harnesses and the side rings of positioning belts sold into that market. Buyers should still confirm the exact standard and the test documentation their product requires. Forging plus heat treatment gives toughness, and the per-piece proof load screens out flawed parts before assembly.

If a stamped alternative with the same ratings is preferred, the 116 in this category is made from sheet alloy steel. Dimensions and finish for the 406 are not listed for this model, so request a drawing and specify webbing width, plating and marking. Power Honour can make the 406 for OEM or private-label programmes and can tailor it to a customer drawing.
